Let’s Make it together
**Preheat Your Oven**: Start by preheating your oven to 375°F (190°C). It will become your sweet potato haven soon enough.
**Prepare Sweet Potatoes**: Peel and slice sweet potatoes into thin rounds. Aim for consistency; they should be about 1/8 inch thick for even cooking.
**Sauté Garlic**: In a skillet over medium heat, melt butter and sauté minced garlic until fragrant. You want it golden but not burnt—nobody enjoys that bitter taste.
**Layer It Up**: In a baking dish, create layers starting with sweet potatoes followed by sautéed garlic and heavy cream. Repeat until ingredients are used up.
**Add Cheese & Seasonings**: Sprinkle salt, pepper, nutmeg, and half of the cheddar cheese between layers. Top everything off with remaining cheese for that glorious crust!
**Bake Until Golden**: Cover with foil and bake for 30 minutes. Then remove foil and bake another 15-20 minutes until bubbly and golden brown—your kitchen will smell divine!
